Update: Earl Hammon, Jr from Infinity Ward has written to me to explain the r_gpusync issue. Basically the game's developers are aware of the additional FPS possible when r_gpusync is disabled (set to 0), however because this setting controls the synchronization of the CPU and GPU (your graphics card(s)), disabling this can also introduce input (mouse/keyboard) lag. This is because your input can at times be processed by the CPU faster than it can be drawn on screen. So on balance they chose the default of r_gpusync = 3 to maintain synchronization while still giving good performance. The same situation (input lag) can occur if the 'Optimize for SLI' or r_multigpu setting is enabled.
seems like 3 is the default anyway so yea 3 is the best but doesnt give more fps
www.tweakguides.com/COD2_10.html there is no input lag chill bro
